Gender theory vs. NIBD
First of all, we should refer to Dick Swaab's book "We are our brains".
Unfortunately, gender theory, which originated in the humanities, is now also being used by doctors and psychotherapists. First of all, we have to distinguish between originally transsexual people (NIBD - Neuro Intersexual Body Discrepancy) on the one hand and transgenders / transvestites on the other.
NIBD means nothing other than that, due to a prenatal (prenatal) disposition, the gender-neuronal connection in the brain has developed in the so-called stria terminalis in the hypothalamus, more precisely in the BSTc (determining the gender self-perception "I am a man", "I am a woman"), in addition to the primary sexual characteristics.
NIBD is congenital, but is overcome through transition, and afterwards those affected generally live a completely normal, inconspicuous, sexus-correct life as a man or woman, both in everyday life and in their sexuality. The physical suffering typical of originally transsexual people (NIBD), partly due to the "phantom feelings", creates a very strong intrinsic motivation that usually leaves no other option than to undergo sexual and genital reassignment surgery.
NIBD sufferers do not feel that they belong to a third sex, i.e. they perceive themselves as clearly male or clearly female and therefore classify themselves in the green circle (see illustration above). With a bit of luck, they can no longer be distinguished from a cis woman or a cis man (cis = if everything went right from birth), either externally or in terms of their charisma. The aim of an NIBD sufferer is to overcome the diagnosis through sex reassignment surgery and to come as close as possible to the cis role model. To be inconspicuous and disappear once the transition is complete. They leave others alone and want to be left alone themselves. Missionary behavior is alien to them.
Transgenderism, on the other hand, is a social construct about the psychological conflict situations of those affected with regard to their social gender role. Because the English word "gender" means nothing else.
Social gender role = gender
Physical sex = sex (as it is also written in the German passport in English; in this context we prefer the Latin term "sexus").
In order to be able to live out the other gender role to some extent without reprisals, many transgender people undergo a partial transition. They take hormones and have their upper body surgically altered. There is usually no intervention "down there", as the motivation for this would be extrinsic, but is not intrinsic. And this is where the wheat is separated from the chaff. Transgenderism has nothing to do with transsexuality (NIBD).
The attitude is also different. After transitioning, people with NIBD generally go into hiding and don't come out unless they absolutely have to. Transgender people, on the other hand, do not overcome their "trans-ness", they remain trapped in their eternal trans-ness and are often proud to stand out, they want to be noticed and live "out-and-proud".
Why NIBD as an addition? Quite simply, because of the appropriation of transsexual people by the transgender community and their favored gender theory. NIBD sufferers are a thorn in the side of the transgender community because they do not fit into their concept of "gender is inherited" (founded by John Money with the failed experiment on the Reimer twins). Life is often made difficult for the silent majority of NIBD sufferers, who (want to) go into hiding and live "stealth" without being outed, by the fact that transgenderism has recently, and increasingly, degenerated into an all-encompassing "one-size-fits-all" approach, which even reinterprets the painful physical phenomena of original transsexuality as "transgender". This serves above all the advantageous thinking of the transgender movement and harms the originally transsexual affected persons (NIBD), especially when transgender people mistakenly suddenly call themselves transsexual, when they otherwise demonize this term. And because of this inflationary use of the term "transsexuality", we suggest that originally transsexual people (NIBD) use the suffix "NIBD" for themselves in order to distance themselves from the transgender problem.
